7. 30% (17°)
The differences in position and depth between the projected depth point and
the actual location of the transmitter can be relatively small at low pitch
and/or shallow depth.
When drilling at a steep pitch and/or significant depth, the differences are
greater.
For example, if the transmitter is at a -30% pitch and a 33'1" (10.1 m) depth,
the locator depth reading will be 35' (10.7 m) (just under 6% difference from
actual depth) and the locate line will be 6'6" (2 m) ahead of the transmitter.
You can use the pitch and the projected depth reading on your locator to
determine the actual depth and the position (fore/aft) of the locate line:
